I was able to reproduce the error by staring up a node using RandomPartioner, kill it, switch to OrderPreservingPartitioner, restart, kill, switch back to RandomPartitioner, BANG!
So it looks like you tinkered with the partitioner at some point. This has the unfortunate effect of corrupting your system table. I'm trying to figure out a way to detect this and abort before data is overwritten. Gary.
